Common peroneal nerve
The common fibular nerve (common peroneal nerve; external popliteal nerve; lateral popliteal nerve) is a nerve in the lower leg.
The common peroneal nerve is the smaller and terminal branch of the sciatic nerve which is composed of the posterior divisions of L4, 5, S1, 2.
It courses along the upper lateral side of the popliteal fossa, deep to biceps femoris and its tendon until it gets to the posterior part of the head of the fibula.
It divides at the knee into two terminal branches: the superficial fibular nerve and deep fibular nerve, which innervate the muscles of the lateral and anterior compartments of the leg respectively.
When the common fibular nerve is damaged or compressed, foot drop can ensue.
